what is broken on the current flake?

[justinmoon]

Doesn't build on MacOS. Sorry I didn't fill out the description better. Late night debugging in discord. https://discord.com/channels/990354215060795454/1096102512169328753/1207888989105684500

I believe this depends on fedimint/fedimint#4349

[Kodylow]

closing this for working #381

[justinmoon]

closing this for working #381

I think this PR should be closed, but to be clear #381 fixes master and this PR fixes releases/v0.2 so we still need to fix releases/v0.2.

[Kodylow]

should we use that same working commit or a different one? and do we actually need to fix it on the release, it's just a dev env issue?

[justinmoon]

We don't need to fix v0.2 if you we won't need to change it at all. Perhaps it's good enough as-is. It seemed like you wanted to change something on v0.2 but maybe I was mistaken.

[Kodylow]

no just needed to change to to get the dev environment working
